Characterisitics of the hall current surrounding a magnetized filamentary plasma

The hall current in the periphery of a filamentary plasma with the inwardly directed radial electric field, Er has been investigated experimentally by utilizing a TPD type dc discharge. When the cusp magnetic filed B$\theta$ is applied perpendicular to the stationary background magnetic field Bz, the hall current by the ErxB$\theta$ drift of electrons is induced in the periphery of the magnetized filamentary plasma.
